in Patent No. 1,039,715, October 1, 1912, the,

application for which was co-pending herewith.

The object of the present invention is to provide an improved machinefor filling battery grids with paste, for packing the paste therein andfor trimming ofi the surplus and giving a finished appearance to thecompleted product.

The machine illustrated in the accompanying drawings represents thepreferred embodiment of the invention.

The views in the drawings are as follows:

Figure 1 is a side elevation of the machine I partly in section. Fig. 2is a top plan view thereof. Fig. 3 is an end elevation thereof. Fig. 4is a sectional elevation through the paste receptacles. Fig. 5 is anelevation of the outlet side of the paste receptacles. Fig. 6 is asectional elevation taken centrally through Fig. 5. Fig. 7 is anelevation of oneof the grid holders. Fig. 8 is a top plan view thereof.Fig. 9 is an elevation of a detail. Fig. 10 is a top plan View of one ofthe scraping blocks. Fig. 11 is a section thereof on line 11-11 of Fig.10. Fig. 12 is a side elevation of a detail. Fig. 13 is a plan view ofan automatic latch.

The following brief description will serve to render clear the mainelements of the machine and the operation thereof. The oxids or paste issupplied to two suitable hoppers and is fed by two screw conveyerstoward a common point from opposite directions. The battery grids orframes which are to be pasted are fed in continuous succession throughan opening near the adjacent ends of the screw conveyers, one of whichis arranged above the other. The screw conveyers force the paste intothe battery grid from above and below the same simultaneously as itpasses through the said openmg. Su1table scrapers are arranged, betweenwhich the filled grids must pass as they are leaving the conveyers.These scrapers pack the paste into the grid, trim off the surplus paste,and give a smooth finish to the surface of the battery grid.

The details of the machine will now be described. A suitable bed plateor table 1 is supported by legs 2. The paste receptacles and conveyersare located preferably above said bed plate and the driving mechanism islocated below said bed plate. Power ls transmitted to the pulley 3 andtransmltted therefrom through the gears 4, 5 to the middle member 6 ofthe differential gear. The other two beveled gears 7 which go to make upsaid differential gear are rotated in opposite directions by said middlemember 6 and through the sprocket wheels 8, 9 and connecting chains 10,the screw conveyers 11 are rotated in a direction to feed the paste fromthe hoppers 12 toward the opening 13. The pulley 3 also drives directlya beveled gear 14 which meshes with a second beveled gear 15, on thesame shaft with which, is arranged a pulley 16 from which a belt 17drives a second pulley 18. On the same shaft with the pulley 18 is abeveled gear 19 driving a second beveled gear 20 which rotates a screwthreaded shaft 21. This shaft rotates continuously and is adapted tocause the carriage 22 to travel from left to right as seen in Figs. 1and 2. Said carriage slides in suitable ways 23. Its engagement with thescrew threaded shaft 21 is efiected through a block 24 having screwthreads which fit the screw threads of said shaft 21. Said block may bemoved into mesh with the threads on the shaft 21 by manipulating theoperating handle 25. The details of this arrangement are shown in Fig.9. The operatin handle 25 is preferably a continuation 0% the rod 26which is provided with an eccentric 27 turning loosely in an opening inthe block 24. Said block is received in an opening 28 in the carriage 22and is guided by the walls of said opening whereby it may be moved backand forth by partial rotation of said eccentric. When the carriage 22reaches the limit of its forward travel, the block 24 is automaticallypushed aside to cause the disengagement of the same from said screwthreaded shaft 21.

The automatic means for disengaging the half nut from the screw threadedshaft is shown more particularly in Figs. 2, 12 and 13. The shaft 26 isprovided at one end with an enlarged hub 29 which is rotatably mounted1n the bracket 30, the latter being cast preferably as part of theframe. The

springr3l. The hub 29 carries a pin 32 (see Fig. 13). Said pin engagesthe inner end of the lever or latch 33 whenever the handle '25 is invertical position and consequently maintains the half nut in engagementwith the screw threads on the shaft 21. The latch 33 is pivoted at thepoint 34 and is normally held n the position shown by a spring 35, theaction of which is resisted by an adjustable stop 36. Whenever it isdesiredto return the carriage 22, the operator grasps the handle 33 andimparts a slight rotation thereto, thereby releasing the in 32 andpermitting the spring 31 to roc the shaft 26 to its normal position,thereby disengagiililgfthe half nut 24 from the screw threaded s a t.

If the latch is not operated by hand, the same is operated automaticallyat the end of the forward travel of the carriage by means of theprojecting pin or arm 37 which strikes the latch 33 and thereby releasesthe pin 32 in the same manner previously described.

The empty grids are adapted to fit into the opening in the frame or gridholder 38 shown in Figs. 7 and 8. Said grid holders are preferablyrecessed at one end, as shown at 39, and provided with a double bevel atthe other end 40 whereby each holder may fit into and be locked in thepreceding holder when the holders are being moved in a continuousseries. Said holders are guided by the ways 23 and advanced by thetraveling carriage 22 and thereby forced in continuous successionthrough the opening 13 of the' pasting device.

It is apparent that the carriage 22 may be released and drawn back atany time to permit the insertion of additional grid holders between saidcarriage and the last grid holder of the recedmg series. In other words,the mac ine' may be kept in almost continuous operation with an endlesssuccession of grid holders and grids passing through the opening andreceiving paste from the screw conveyers.

As the grid holders which contain the grids advance to the opening 13,they pass under and are held down by a spring pressed roller 41. (SeeFig. 6.) Said roller may be when desired. rced int'p the grids both fromabove and below,'as w1l1 be apparent from an inspection-of this figure.

As the grid emerges, it passes between a pair of spring pressed scrapingblocks 43, one of I which is shown more in detail in Figs. 10 and 11.Both blocks on their adjacent faces are provided with diagonally.-arranged ridges44. These ridges scrape ofi the surplus paste' and alsoserve to further" ackthe paste-into the grid. The diagona arrangement ofthe ridges has been found to result in a very eflectiv'e packin andscraping action. The plate is furt er, scraped smooth and given afinished appearance by passing between the yielding bla as 45; The

nished grid as it passes these scrapers may be received on to a suitabletable, traveling belt or other suitable support, or may be removedmanually if desired.

In the above machine the grids move in a horizontal plane, as they arebeing pasted, and accordingly one paste conveyer is arranged above theother. Of course, I do not limit myself to this relative arrangement ofthe parts, nor to the other details of construction and arrangement ofparts shown and described. In general, I desire to cover suitableequivalent means for accomplish:

ing the desired results whenever said means fall within the scope of theap ended claims.
